# Expert Advice:

01 -
  • The fish stays impossibly tender because you're not fussing with it—just a gentle bake and it's done.
  • That relish is bright enough to feel special but takes five minutes to throw together while the oven works.
  • It tastes like restaurant food but comes together faster than ordering takeout.
02 -
  • Wet fish steams instead of bakes, so those paper towels are doing real work—don't skip that step or you'll wonder why it tastes pale and sad.
  • The relish needs to be made fresh and served immediately; if you make it an hour ahead, the tomatoes break down and it becomes mushy rather than vibrant.
03 -
  • Buy halibut from a fishmonger if you can rather than pre-packaged; they'll cut it to the thickness you want and the quality difference is real.
  • If your cherry tomatoes are watery, quarter them and let them sit in a colander for five minutes to drain before adding them to the relish.
